Definitions
- the invention relates to a rim or set of elements constituting a rim for the mounting and rolling a tire without an independent inner tube or "tubeless”, and intended more particularly for equipping heavy vehicles.
- rims of commonly used rolling assemblies we we can distinguish mainly rims called hollow base, having seats frusto-conical inclined to the axis of rotation of the assembly at an angle of 5 ° or 15 °, and rims with a flat or practically flat bottom having seats inclined at 0 °, either at 5 ° to the axis of rotation.
- the so-called hollow base rims have a mounting groove whose diameter is significantly smaller than the nominal rim diameter.
- This inner diameter of the rim is considered by users to be too small because it does not allow to choose by example of brake drums of dimensions adapted to effective braking of vehicles more and more powerful in relation to their weight.
- said rims are commonly used for mounting and rolling by example of Passenger and / or Truck tires, but they are very less and sometimes not at all for other types of vehicles, such as, for example, construction and civil engineering machinery.
- a flat-bottom rim For mounting the so-called "tubeless" tire, a flat-bottom rim requires the presence of at least one removable side ring, a locking ring and a seal, and obviously the rim tape with a fixed edge on the side opposite the side where the parts are removable. A minimum of three pieces is therefore required. In most cases, the number of parts required is more than three and may sometimes reaching six pieces for large tire sizes. Exception made of rubber seals, the parts of a rim are metallic, and consequently heavy, bulky, and difficult to handle. It follows that assembly and disassembly of large and very large tires are difficult and time consuming operations. Installation and / or removal of a wheel fitted with such a tire require the immobilization of the vehicle or the craft for a significant period.
- the metal parts used that are the conical rings, the flanges, the locking rings are often subject to partial, localized wear, with or without oxidation and formation of rust, damage which results in the subsequent use of defective fittings with pressure losses but also creation of stress concentration which can cause breakage of parts.
- the rubber seals vulcanized require, as known per se, a lot of care in their placement; in addition they are subject to natural oxidation and poor storage conditions, hence the appearance of numerous cracks; so, and in many cases the conditions are such that said seals do not satisfactorily fulfill the role for which they were intended.
- the invention proposes a new assembly assembly for a tire without independent inner tube, comprising at least two metal conical rings intended to receive the tire beads, said two metal rings being positioned and locked on the vehicle hub by means of two rings of lateral, circular locks, each made of a mixture of rubber vulcanized reinforced by and encasing a circumferentially reinforcing ring elastic and radially resistant to compression, and being placed in a recess in the hub.
- a circumferentially elastic reinforcing ring must be understood to mean an element whose circumferential development is likely to lengthen by at least 3% under an effort of at most 50 daN, and returning to its initial state when the effort is deleted.
- radially compressive strength reinforcing ring is meant a ring whose maximum radial dimension of its cross section, that is to say the greatest radial distance between two points of the contour of said section located on perpendicular to the axis of rotation of the rim, is reduced under effort by at most 2%.
- conical mounting ring is meant a ring having radially to the outside a seat whose generator makes with the direction of the axis of rotation a certain angle, but also a ring whose seat has a generator making with said axis a zero angle.
- a mixture of vulcanized rubber or vulcanizate is understood to mean a mixture elastomer (s), reinforcing fillers and well known additives which are vulcanized to a certain temperature.
- the coating mixture of the ring of reinforcement will have a secant modulus of elasticity under a relative elongation of 10% at least 6 MPa.
- US 5,259,430 describes a mounting assembly for a tire according to the preamble of claim 1.
- FR 2 087 770, US 4,706,723 and US 5,890,526 describe other mounting assemblies for tires without independent air chamber.
- a circular ring of rubber reinforced by a circular reinforcement ring is described in patent FR 2 677 304.
- Said rubber ring is in the cited patent used as an adapter, i.e. a means having a cross-section chaise longue adapted so that you can mount tire beads having a given configuration on rims intended for receive beads of another configuration.
- the ring thus used is a ring mounting of beads with, in particular, a radially outer wall of meridian profile identical to standard profiles, when it comes to mounting a tire meeting the standards in force.
- the invention uses such a ring reinforced rubber in a suitable form, not as an adapter or ring mounting, but as a locking ring, the mounting rings being, in the part of the invention, metallic and not rubbery.
- a locking ring according to the invention is described in claim 1. It is considered to have at minus two walls: a radially inner wall and a radially wall exterior, said two walls being able to be joined by quasi-perpendicular side walls to the direction of the axis of rotation.
- the radially inner wall has a shape that is similar to the shape or profile of the recesses or grooves created on the hub of the machine for receiving said rings.
- Said recesses can have, seen in meridian section, any shape but preferably have a section meridian whose surface is almost triangular with a base on the generatrix of the hub and with two sides forming with the direction parallel to the axis of rotation of the acute angles can be between 10 ° and 45 °, the two sides being joined at opposite of said base by a rounded apex, to minimize the concentrations of stresses and the risk of fatigue cracks.
- the quasi-height of said triangle, lowered from the rounded top on said base is preferably between 10 and 45 mm.
- the radially inner wall of the locking ring a, in section meridian, a profile identical to the interior profile of the quasi-triangle above.
- the meridian section of the reinforcement ring of the locking ring in its radially inner part, can be of any shape insofar as a important part of the maximum radial dimension of its meridian section is included in the triangular section of the recess in the hub. It is necessary hear by significant part a radial distance at least equal to 25% of the maximum radial dimension of reinforcement ring section.
- Said part radially inner of the reinforcing ring can have two shapes preferential: elliptical (the circle being considered as an ellipse) and polygonal with at least two sides substantially parallel to the two sides of the section triangular of the hub recess, which allows the correct positioning of the elastic locking ring and to maintain said positioning despite the stresses or stresses arising with inflation, and crushing, and rolling tire.
- the meridian section in the radially outer part of the ring locking can also be elliptical in shape, but will preferably be composed of at least a frustoconical part whose generator does with the direction of the axis of rotation an angle which can be between 15 ° and 35 °. Said part frustoconical will come during the mounting of the tire opposite the part frustoconical of the radially inner wall of the conical ring on which will be mounted the tire bead.
- the meridian section of the ring of reinforcement, in its radially outer part, can then be elliptical, circular or polygonal with, in the latter case, one side parallel to the part frustoconical of the radially outer wall of the ring.
- a individual coil can have any cross section, but it is preferably circular and the diameter of the cross section of the coil is, in depending on the dimensions of the spring, between 2 and 8 mm, which allows deformation of the turn under compression force, less than 2%.
- the ring of reinforcement can also be a succession of cylindrical elements made of rigid material, such as steel or ceramic material, said elements being of shorter length to the diameter of the cylinder and joined together circumferentially by a mixture of Shore A high hardness rubber.
- the compressive strength of said spring may be advantageously improved by the insertion inside the turns, either of an element continuous and circular in vulcanized rubber of high Shore A hardness, i.e. continuous and circular plastic element, said elements being circular discontinuous to maintain the elasticity of the spring.
- Said spring in order to facilitate the operations of dismantling the tire and for removing the locking ring, is fitted with a metal cord or strap allowing by means of a tensile force exerted on said cord to dislodge the hub recess ring.
- the metal mounting ring is a metal element composed of a seat rim, generally frustoconical but possibly cylindrical, or other, said seat being extended axially and radially outside by a rim flange, said rim which can possibly be independent of the seat and can be removed from audit headquarters.
- Said ring has a radially inner wall formed by at least one frustoconical part whose generator makes with the direction of the axis of rotation a angle between 15 ° and 35 °, while the radially outer wall, seen in meridian section, is composed on the one hand of a frustoconical generator making with the direction of the axis of rotation an angle may be between 0 ° and 16 °, and on the other hand, extending axially to the outside of said generator by means of an arc of a circle, of the curve representative of the axially inner and radially outer profile of the flange of rim.
- Said curve is in all cases advantageously located radially to outside and axially inside a line segment joining the point of intersection of said curve with the frustoconical generator above and the point of said curve furthest from the axis of rotation.
- said curve can be formed of a circular arc tangent to the connecting circular arc between the frustoconical generator and the curve. It can also be formed by a line segment perpendicular or not to the axis of rotation, tangent radially inside to the above connecting arc and radially outside at a second arc so as to obtain the curve desired.
- the metal mounting rings can be independent of the tire and more particularly beads of said tire.
- conical rings with seats and edges are part integral with the tire in the same way, for example, as the bead wires; said rings can be made integral with the beads of the tire by a press fitting without possibility of detachment.
- Such a principle is described in patent FR 2,087,770 of the applicant.
- the metal rings of mounting beads are advantageously provided in their parts axially interior of an air cushion system, which allows to have and keep during mounting operations a free space between the hub and the radially inner part of the rings, hence an axial displacement greatly improved.
- Said free space of 5 to 20 mm is also intended to allow commitment to view of the hub without jamming the tire-metal ring assembly.
- FIG. 1 only the bead (4) of a large tire is shown. and intended to run on a Civil Engineering machine. Said bead is mainly reinforced by a rod (41) around which is anchored by winding the radial carcass reinforcement (40) of said tire.
- the bead (4) has walls radially inner and axially outer in shape and dimensions provided for be mounted on a metal mounting ring (3), consisting of a seat frustoconical (31) including the generator (310), seen in meridian section made with the direction of the axis of rotation an angle of 5 ° ⁇ 1 °, generator axially extended to the outside by an arc (330) connecting said generator (310) to the wall (320) a rim flange (32), said wall (320) being perpendicular to the direction of the axis of rotation and ending axially and radially on the outside by a rounding (340).
- the dimensions of the generators (310) to (340) are of standardized dimensions.
- the wall radially inner of the conical mounting ring (3) is formed mainly of an obviously (303), extended axially outside by a frusto-conical part (301), the generator of which forms with the direction of the axis of rotation an angle ⁇ , open axially and radially inward and equal to 30 °, itself extended by a generator (302), cylindrical in the example described, and the trace of the axially outer wall of the flange (32). All generators (301) and (302) are in contact with the radially outer wall of the locking ring removable (2), said wall also being formed, seen in meridian section, by two generators (203) and (204) having the same characteristics as the generators (301) and (302) respectively.
- Said locking ring (2) is composed of a mixture of vulcanized rubber (21) reinforced by a ring of reinforcement which is a spring (20) of circular section and obtained by winding helical contiguous with a metallic coil of brass-plated steel of equal diameter at 4 mm.
- the helical winding is done around a continuous and circular element (22) of vulcanized rubber mixture with high hardness Shore A, equal to 93.
- the radially inner face of the locking ring (2) in reinforced rubber is formed by the two frustoconical generators (201) and (202) which will come into contact and rely on the two frustoconical generators (101) and (102) respectively of the circular recess (10) created in the hub (1).
- said generators form with the extension of the cylindrical generator (11) of the hub (1) an isosceles quasi-triangle with two sides (101) and (102) forming with the direction of the axis of rotation or of the generator (11) which is parallel to it an angle ⁇ substantially equal to 35 ° and a base of sufficient axial width for at least the third of the diameter D of the spring (20), which is the maximum radial dimension of the ring reinforcement (20) is located inside the quasi-triangle defined above, which allows in combination with the shape of the recess and the shapes radially inside and outside of the ring (2), the axial locking necessary and sufficient for the maintaining said ring (2) in all driving conditions.
- a strap (5) is wrapped around the meridian section of the reinforcement ring (20) of the locking ring (2) to allow, after deflating the tire and displacement of the bead axially inwards, dislodging of said ring (2) of its housing which is the recess (10) of the hub (1).
- the recess (303) in the axially inner part of the metal mounting ring (3) makes it possible to house a positioning and centering system for the mounting assembly (2, 3) on the hub (1).
- Said system consists of a chamber (8) or a succession of chambers covering a portion of the circumferential surface of the mounting ring between 30 and 80% of the total surface.
- Said chambers each contain an elastomeric seal and are supplied with gas by a specific network (7) or by the tire inflation circuit, the seals being pushed back into the chambers, thereby closing the openings xx 'which can be communicating towards the outside or inside; part of the flow flows through the openings yy 'and by leakage between the lips of the seal and the hub ensures an air cushion effect.
- the pressure increase in the upper chamber (8 1 ) pushes the seal and restores the concentricity of the seat. Said state of concentricity and elimination of friction makes it possible firstly to set up the external locking ring (2) and secondly to guarantee the engagement of the parts (301) and (302) previously described.
- the quasi-triangular shape of the recess (10) is not more isosceles, but with an axially outer side less inclined to the axis of rotation than is the axially inner side. Locking required and sufficient will be obtained with an appropriate form of the reinforcing ring (20), which is a spring of rectangular section, two adjacent sides of which are parallel to two sides of the quasi-triangle of the recess (10).
- Figures 1 and 2 use beads of constitution and shape usual for mounting on walls of mounting rings which are standardized (TRA, ETRTO), the bead shown in Figure 3 and the profile radially inside the mounting ring, adapted to said bead, are not usual.
- the the tire bead shown in FIG. 3 does not have a bead, the carcass reinforcement anchoring and rim tightening functions are provided by the presence of several reinforcements (41, 42) of suitable constitutions, presence combined with a meridian profile of carcass reinforcement as described by example in international application PCT / EP 98/06832, and the meridian profile of the mounting ring seat (31) which can itself be adapted to the frame profile of carcass.
- the carcass reinforcement is, in each bead, at least radially at outside and axially inside reinforced by at least a first layer additional (41) continuous comprising at least a first part composed of at least minus a ply formed of inextensible reinforcing elements making with the circumferential direction an angle between - 2.5 ° and + 2.5.
- a first layer additional (41) continuous comprising at least a first part composed of at least minus a ply formed of inextensible reinforcing elements making with the circumferential direction an angle between - 2.5 ° and + 2.5.
- Axially to the outside and radially inside is advantageously arranged a second additional layer formed by at least a first part of at least one ply inextensible and circumferential reinforcing elements.
- the meridian profile carcass reinforcement (40) in the tire bead is formed, in the extension of said profile in the sidewall, by an arc of a convex circle BC extended tangentially and axially inside by a straight line CD, D being the end of the carcass reinforcement (40).
- the meridian profile of the wall, seen in meridian section, radially inner (31) of the metal mounting ring (3) is similar to the profile of the carcass reinforcement as defined above, since formed an arc of a circle extended by a frustoconical generator.
- the rest of the mounting assembly and in particular the locking ring (2) it is practically identical to the ring described and shown in Figure 2, except for the slightly changed.
